Effective Algae Control & Eradication for Institutional Pools

Algae spores are constantly introduced into outdoor swimming pools by wind, rain, bathers, and fallen leaves. Once algae takes root in warm Indian temperatures, it multiplies exponentially, turning a crystal-clear pool into a slippery, green health hazard within hours. This comprehensive guide outlines the exact 5-step eradication protocol used by professional pool technicians.

1. Identifying the 3 Common Types of Pool Algae

Different algae species require tailored chemical strategies for complete elimination:

• Green Algae (Chlorophyta): The most common form. It turns water murky green and makes pool floors slick and hazardous. Responds quickly to TCCA 90 shock chlorination.
• Mustard / Yellow Algae (Phaeophyta): Resembles yellow sand or pollen clinging to pool corners and shaded walls. It resists low chlorine levels and requires targeted brushing.
• Black Algae (Cyanobacteria): Forms dark, stubborn spots in tile grout and plaster cracks. It builds a thick protective waxy sheath that must be mechanically scrubbed before chemical application.

2. The 5-Step ShubhamEnterprise Algae Eradication Protocol

Step 1: Test and Adjust Water Balance

Ensure pool pH is adjusted to 7.2 to 7.4. Chlorine is significantly more effective in slightly lower pH environments during shock treatments.

Step 2: Vigorous Wall & Tile Brushing

Scrub all pool surfaces thoroughly using a heavy-duty nylon or stainless steel pool brush. Brushing destroys the outer protective membrane of algae, allowing chlorine to penetrate directly into algae roots.

Step 3: Super-Chlorination (Shock Treatment)

Dissolve 500 grams of Shubham TCCA 90 Powder per 50,000 Liters of water in a bucket of warm water, then pour evenly around the pool perimeter. This raises free chlorine concentration to 10-15 ppm, killing 99.9% of algae spores.

Step 4: Continuous 24-Hour Filtration & Flocculation

Keep the filtration pump running non-stop. For cloudy dead algae suspension, add 100 ml of Shubham Poly Aluminium Chloride (PAC) Liquid Flocculant to settle dead particles to the pool floor for vacuum removal.

Step 5: Deep Filter Backwashing

Once water clears, perform a thorough backwash of the sand filter for 3 to 5 minutes to prevent trapped dead algae from re-contaminating the pool system.
